The thing is you dont have to build some imaginary number of 'aheadness' in enmity. You just look at the white bars in the party list. If you have all of 2 pixels ahead of the #2, then you need to generate some enmity. If you have a large gap continue to do DPS until that gap becomes close again. Once you get more comfortable with your jobs timings, you will know when you do and dont need enmity. EG: If my IR window is 10 seconds away and i see people closing in, I know I can survive until i spam out double damage Fell cleaves and the free double damage onslaught with a 10x enmity modifier to put me back ahead. If I am 40 seconds away from IR and they are closing in I use my brain and realize I need to burn some onslaughts or use a butchers to tide me over, etc.

You dont need some absurd 300 THOUSAND enmity lead to afk until shirk is up. You just watch the stupid bars and if they are close, you make enmity. If they arent you dps. Yall really trying to over complicate this.

If HP is low, healers heal. If HP bars are high you dont. If white enmity bars show a large lead you dps. If they are close you enmity up some.
